DIY alcohol burners are good,cheap equipment. There are many types,including many made from coke cans,many of which are more or less copies of the Trangia type. They tend top be a bit fiddly to use,and because of the need to "bloom" (develop vapour pressure to have sufficient pressure to force vapour out of the jet holes) they don;t work very well in cold temperatures. I think that the so called "fancy feest (feast) type stove is the most reliable and simple to use alcohol stove. They even light reliably in -20 deg C. Developed by Zelph(I think) of zenstoves.com. Here is a video:

Another wick stove using a cat food can puts a wick around the outside of a can:

This also works reliably, and if using a tuna can, has a fairly wide, stable base,
Another favpurite of mine is the capillary action stove, which is really easy to make using just a soda can and a knife (or scissors) if you don't have any wick material readily available. The crimping can be done with a knife blade of some long nose pliers. It blooms much more quickly than most pressure stoves(penny stove, white box, trangia), so is more reliable.

Like all alcohol stoves, they need a good windscreen to work effectively.They are pretty good at boiling water (16 fluid ounces in 4-41/2 minutes) . Simmering/slow cooking require additional tweaks to block off some of the fire ring. It can be fun developing and making those. Lots of you tube videos available.
I use them because they are effective, and very light (10-15 grams for the capillary type) so are good for hiking/backpacking. Even the two can fancy feest only weighs about 30 grams. BTW, you don;t have to use carbon felt for the wick. glass fibre tape works just as well and may be more easily available. I have even used kitchen roll paper and cotton string to make wicks (a thin wick gives a smaller flame for a simmering stove)
Be careful,you may find that DIY alcohol stoves can be a trifle addictive.
